Solar in Cranbourne — What You Need to Know

Cranbourne sits in Melbourne's outer southeast and enjoys marginally more sunshine than the inner city due to reduced urban heat island effects and clearer skies. Casey Council's rapid suburban growth means a mix of older concrete tile homes and newer colorbond rooftops — both ideal for solar. The area has seen massive housing development since 2000, and newer homes are increasingly built with solar-ready wiring. Cranbourne's growing population skews young-family, with high energy consumption (reverse-cycle systems, pools, EVs) making solar ROI excellent. The Solar Homes Program applies and is widely utilised here.

What Size Solar System for Cranbourne?

The right system size depends on your electricity usage. A quick rule: divide your quarterly bill by $100 to get your ideal system size in kW. For Cranbourne, common household sizes are:

5kW 1–2 people · $53/yr 6.6kW 2–4 people · $70/yr 10kW Large home / EV · $106/yr

With NSW's feed-in tariff at 5.5c/kWh and electricity at 33c/kWh, the priority is maximising self-consumption rather than grid export. If your household is away during peak solar generation hours (10am–3pm), adding a battery to shift solar to evening use improves payback. See our solar battery guide for battery options and payback analysis.
